fix(cli): bump svelte version in wmill app new template (#9084)

* fix(cli): bump svelte version in `wmill app new` template

The svelte5 template pinned `svelte` to `5.45.2`, but the Svelte
compiler bundled in `wmill app dev` emits `$.delegated('click', ...)`
calls. The `delegated` export was added later, so 5.45.2 doesn't have
it — esbuild warns `Import "delegated" will always be undefined`,
replaces the call with `void 0`, and the page crashes at first
event-handler bind (white screen).

Bump to `^5.55.5` so the compiler and runtime stay in sync.

* fix(frontend): bump svelte version in raw_apps UI template

Mirror the CLI fix: the UI's `Add raw app` flow scaffolds a
package.json with `svelte: "5.45.2"`. That works today only because
the bundled rolldown worker also pins 5.45.2 — when the worker is
upgraded past 5.51.1, the compiler will emit `$.delegated()` and the
runtime won't have it, producing the same white-page crash that hit
the CLI.

5.55.5 still exports `event` (used by the current bundled compiler),
so this is forward-compatible: it works with the 5.45.2 compiler now
and won't break when the worker is upgraded.
